The hybrid-pipeline master scene as an animated gate. It builds up from cascading glyph-lines — plinth, doorway tunnel, then a recursive binary-tree tympanum — holds fully constructed, then dissolves bottom-up in a refined ASCII fashion. Loops.
Thick vertical teal lines rise to build the gate. When complete, lighter lines cascade outward from the horseshoe center. Then it disintegrates bottom-up into sparkling gray symbols — and at the seam between the still-teal and the gone-gray, white symbols flash like sparks crossing the threshold.
